We study pK- scattering in the energy range from threshold through the 
(1520) peak in UBChPT, taking into account O(q) vertices from meson-baryon contact interactions and s - and u -channel ground-state baryon exchange, s - and u -channel decuplet- and nonet-baryon exchange and t -channel vector-meson exchange, as well as O(q
2) flavor-breaking vertices. Detailed fits to data are presented, including a substantial body of differential cross-section data with meson momentum q
lab > 300 MeV not considered in previous treatments.
